Improved steam-boiler



UNITED STATES PATENT OFFICE.

M. S. BRINGIER, OF NEIV ORLEANS, LOUISIANA.

IMPROVED STEAM-BOILER.

Specication forming part of Letters Patent No. 25,802, dated October 18,1859.

To @ZZ whom, t may concern.-

lSe it known that I, M. S. BRINGIER, of the city of New Orleans, parishof Orleans, and State of Louisiana, have invented a new andusefullmproved Steam-Boiler; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, similar letters of referenceindicating like parts in all the figures.

Figure l is a longitudinal vertical section; Fig. 2, a side elevation;Fig. 3, a plan or top view; Fig. et, an end view of cross-section atline indicated at G G.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A A are two cylindrical chambers or short boilers made in the usual formof cylinderboilers; B B, a series or quantity of horizontal tubes orpipes connecting the two cylindrical chambers A A together at the lowerportion of their opposite heads; C, a cylinder of Inuch larger capacity,having an area about equal to the sum of the area of the tubes on thelower portion. This connects the upper portion of` the cylindricalchambers together at their opposite heads over the tubes, the top ofthis cylinder being level with the top of the said chambers A A.

rlhe advantages of this form of boiler over any other now in use are,first, its perfect applicability for all purposes of high or lowpressure steam .with as much safety as an ordinary cylinder-boiler;secondly, exposing more effective heating-surface to the action of thefire than any internal tubular boiler of equal surface, and at the sametime a much more perfect combustion of fuel can be obtained under theboiler than can possibly be done or obtained in an ordinarytubular orlocomotive boiler, where the lia-me is at once, on leaving the fuel,forced into a number of small tubes before a proper or perfectmixture ofthe combustible gases can have taken place, hence causing a large lossof heatingsurface from the deposits of unconsumed carbon in the interiorof the tubes.

The cylindrical chambers A A render this application of tubes B B B Bperfectly safe, as they act as water and steam reservoirs. A sufficientamount of water can be held in this form of boiler to rcnderit veryeasily attended to, and a perfect equilibrium is maintained in the twochambers A A. by the large connecting-cylinder O.

That- I claim as my invention, and desire to secure by Let-ters Patent,in the above-described boiler for generating steam, is-

The arrangement of a series of horizontal tubes or pipes connecting twocylindrical chambers or reservoirs of waterand steam, in combinationwith the steam-cylinder C, connecting the same chambers, substantiallyas described.
